Description

Uhrglas mit lumineszierendem Element  Watch glass with luminescent element
Beschreibung description
Die Erfindung betrifft ein Uhrglas mit lumineszierenden Elementen. Zifferblätter mit selbstleuchtenden, fluoreszierenden Leuchtpunkten sind hinlänglich bekannt. Ebenso sind dazugehörige Zeiger, die mit selbstleuchtender fluoreszierender Masse angefüllt, vorbekannt. Die Leuchtpunkte auf dem Zifferblatt und die selbstleuchtenden Zeiger zielen darauf ab, dass der Träger der Uhr auch bei Nacht ohne zusätzliches Licht die Zeit auf seiner Uhr ablesen kann. Die bisherigen Methoden einer selbstleuchtenden Ziffern- und Zeiger-Anzeige durch fluoreszierende Substanzen in, oder neben den Ziffern, und auf oder in den Zeigern, haben aber einen entscheidenden Design-Nachteil. Die Zeiger müssen entsprechend dick oder breit sein, um die Leuchtmasse beherbergen zu können. Ebenso müssen sich die Ziffern der Uhr den Platz mit den Leuchtpunkten teilen, oder die ganzen Ziffern müssen so breit sein, dass diese mit Leuchtmasse angefüllt werden können. The invention relates to a watch glass with luminescent elements. Dials with self-luminous, fluorescent luminous dots are well known. Likewise, associated pointers filled with self-luminous fluorescent compound are previously known. The luminous dots on the dial and the self-illuminating hands aim to ensure that the watch wearer can read the time on his watch even at night without additional light. The previous methods of self-luminous numeric and pointer display by fluorescent substances in, or next to the numbers, and on or in the hands, but have a decisive design disadvantage. The hands must be thick or wide to accommodate the luminescent material. Likewise, the numbers of the clock must divide the space with the luminous points, or the whole numbers must be so wide that they can be filled with luminous material.
Im Resultat kollidiert ein filigranes, kunstvoll gestaltetes Design einer Uhr immer mit den Platzanforderungen der Leuchtmasse und wird dadurch eigentlich unmöglich gemacht. As a result, a filigree, ornately designed design of a clock always collides with the space requirements of the luminous mass and is thus actually made impossible.
Es ist Aufgabe der Erfindung, ein Uhrglas vorzuschlagen, bei dem die gesamte benutzte lumineszierende Leuchtmasse platzmäßig reduziert werden kann, ohne die Ablesbarkeit der Uhrzeit bei Dunkelheit zu beeinträchtigen, wobei auch ein ästhetisch wertvolles Erscheinungsbild der Uhr möglich ist. It is an object of the invention to provide a watch glass, in which the entire used luminescent luminous material can be reduced in space, without affecting the readability of the clock in the dark, with an aesthetically valuable appearance of the clock is possible.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1. Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung. The solution of this object is achieved by the features of claim 1. The subclaims show preferred developments of the invention.
Insbesondere erfolgt die Lösung dieser Aufgabe durch ein Uhrglas, welches ein Deckglas, ein Trägerglas, das zum Bilden einer Glaseinheit mit dem Deckglas verbunden ist, und ein lumineszierendes Element umfasst, das in die Glaseinheit eingebracht ist. Die vorliegende Erfindung verlegt die Platzierung der in Form eines lumineszierenden Elements ausgebildeten Leuchtmasse in das Uhrglas. Somit wird erreicht, dass bei der Verwendung des Uhrglases bei einer Uhr die selbstleuchtende Leuchtmasse einerseits ihre Lichtstrahlen direkt an den Betrachter abgibt, und somit eine Zeiteinteilung auch bei Dunkelheit bzw. Nacht deutlich sichtbar macht. Andererseits gibt die Leuchtmasse ihr Licht auch in die umgekehrte Richtung, in den Innenraum der Uhr, wo sich das Zifferblatt und die Zeiger befinden, ab. Somit beleuchtet das lumineszierende Element sowohl die Zeiger als auch das Ziffernblatt, welche unter dem Uhrglas angeordnet sind. Dadurch können die Zeiger, welche frei von Leuchtmasse sind, frei ausgestaltet werden. Ferner können auch andere Elemente, wie die Zahlen des Zifferblatts usw., ohne Design-Abstriche ausgesucht werden und keine Leuchtmasse aufweisen. Somit ist es möglich, die gesamte Menge an Leuchtmasse zu reduzieren, wo die Leuchtmasse stört, nämlich auf dem Zifferblatt und dem(den) Zeiger(n). Dort wird sie auf den Wert Null reduziert. Außerdem kann bei der Verwendung einer Vielzahl von lumineszierenden Elementen ein verbessertes Muster im Hinblick auf die Verteilung der Elemente im Uhrglas erzielt werden, was wiederum zu einem verbesserten Erscheinungsbild des Uhrglases bzw. der Uhr führt. Der große Vorteil der Erfindung besteht darin, dass das lumineszierende Element nicht nur zurück zum Betrachter leuchtet und somit selbst gesehen wird. Vielmehr wird das lumineszierende Element selbst zu einem Beleuchter der gesamten Uhr. Das lumineszierende Element will also nicht nur„gesehen" werden, sondern es will beleuchten. Das Zifferblatt und die Zeiger leuchten nicht, sie werden beleuchtet, wie am Tage oder bei externer Beleuchtung. Dies entsteht dadurch, dass das lumineszierende Element über dem Innenraum des Zifferblatts und den Zeigern in das Uhrglas integriert ist. In particular, the solution of this object is achieved by a watch glass, which comprises a cover glass, a carrier glass, which is connected to the cover glass for forming a glass unit, and a luminescent element, which is introduced into the glass unit. The present invention relocates the placement of the luminescent element in the form of a luminescent element in the watch glass. Thus it is achieved that when using of the watch glass in a watch, the self-luminous luminescent mass on the one hand their light rays directly to the viewer, and thus makes a time division clearly visible even in the dark or night. On the other hand, the luminous material also emits its light in the opposite direction, in the interior of the clock, where the dial and the hands are located. Thus, the luminescent element illuminates both the hands and the dial, which are located under the watch glass. As a result, the hands, which are free of luminescent material, can be designed freely. Furthermore, other elements, such as the numbers of the dial, etc., can be selected without design smears and have no luminescent material. Thus, it is possible to reduce the total amount of luminescent mass, where the luminescent mass disturbs, namely on the dial and the pointer (s). There it is reduced to the value zero. In addition, when using a plurality of luminescent elements, an improved pattern with regard to the distribution of the elements in the watch glass can be achieved, which in turn leads to an improved appearance of the watch glass or the watch. The great advantage of the invention is that the luminescent element not only shines back to the viewer and thus is seen by itself. Rather, the luminescent element itself becomes a illuminator of the entire clock. The luminescent element thus not only wants to be "seen", but it also wants to illuminate the dial and the hands do not light up, they are illuminated, as in the daytime or with external lighting.This is because the luminescent element over the interior of the dial and the hands are integrated into the watch glass.
Im Rahmen der Erfindung sind das Deckglas als ein erstes Glas und das Trägerglas als ein zweites Glas zu verstehen. Das Deckglas entspricht insbesondere dem Glas, welches einem Betrachter zugewandt bzw. einem Boden eines Uhrgehäuses abgewandt ist. Das Trägerglas entspricht insbesondere dem Glas, das einem Betrachter abgewandt bzw. dem Boden des Uhrgehäuses zugewandt ist.„Lumineszierend" bedeutet, dass das Element eine von außen zugeführte Energie, beispielsweise durch die Sonne, ganz oder teilweise nicht seiner thermischen Energie zuführt, sondern von der absorbierten Energie in einen angeregten Zustand versetzt wird und emittiert Licht. Wenn zwischen der Absorption der Energie und der Emission kein Aktivierungsprozess stattfindet, dann spricht man von Fluoreszenz. Wenn ein angeregter Zwischenzustand die Energie für eine gewisse Zeit„speichern" kann, wird dann von Phosphoreszenz gesprochen. Ferner wird ein sehr kurzes Nachleuchten als unmittelbare Folge und Begleiterscheinung der Anregung mit dem Begriff der Fluoreszenz bezeichnet. Auf der anderen Seite bedeutet der Begriff der Phosphoreszenz ein längeres Nachleuchten nach der Anregung. Mit anderen Worten dient der Begriff„lumineszierend" bzw.„Lumineszenz" als Oberbegriff und umfasst die Unterbegriffe der„Fluoreszenz" und der„Phosphoreszenz". Vorzugsweise ist beim Uhrglas mindestens eine Ausnehmung vorgesehen, in der das lumineszierende Element angeordnet ist, wobei die Ausnehmung im Deckglas und/oder im Trägerglas ausgebildet ist. Durch das Vorsehen einer Ausnehmung, in die das lumineszierende Element eingebracht ist, erfolgt die Positionierung des lumineszierenden Elements in kontrollierter Weise, sodass eine Endposition des Elements im fertigen Uhrglas einfach sichergestellt werden kann. In the context of the invention, the cover glass is to be understood as a first glass and the carrier glass as a second glass. The cover glass corresponds in particular to the glass, which faces a viewer or faces away from a bottom of a watch case. In particular, the carrier glass corresponds to the glass which faces away from the observer or faces the bottom of the watch case. "Luminescent" means that the element does not supply all or part of its externally supplied energy, for example by the sun, to its thermal energy If there is no activation process between the absorption of the energy and the emission, then it is called fluorescence, and if an excited intermediate state can "store" the energy for a certain period of time, then Phosphorescence spoken. Furthermore, a very short afterglow is referred to as the immediate consequence and concomitant of the excitation with the term fluorescence. On the other hand, the term phosphorescence means a longer afterglow after the excitation. In other words, the term "luminescent" or "luminescence" serves as a generic term and includes the subordinate concepts of "fluorescence" and "phosphorescence". Preferably, at least one recess is provided in the watch glass, in which the luminescent element is arranged, wherein the recess is formed in the cover glass and / or in the carrier glass. By providing a recess, in which the luminescent element is introduced, the positioning of the luminescent element takes place in a controlled manner, so that an end position of the element in the finished watch glass can be easily ensured.
Besonders bevorzugt ist die Ausnehmung vollständig im Trägerglas ausgebildet. Somit befindet sich das lumineszierende Element näher zu einem Zifferblatt und den Zeigern einer Uhr, die das beschriebene Uhrglas aufweist. Dadurch wird die Intensität der Beleuchtung eines durch das lumineszierende Element beleuchteten Bereiches des Zifferblattes verstärkt. Alternativ kann bevorzugt die Ausnehmung im Trägerglas ausgebildet sein. Somit kann durch das lumineszierende Element ein größerer Bereich des Zifferblattes beleuchtet werden. Ein weiterer Vorteil einer Ausnehmung mit lumineszierender Masse im Trägerglas ist, dass dann das Deckglas frei von Ausnehmungen sein kann. Dies erleichtert die Verwendung von Safirglas als Deckglas, welches sehr viel schwieriger mit einer Ausnehmung zu versehen ist, als das weichere Mineralglas des Trägerglases. Die Verwendung von Safirglas als Deckglas oder Abschluss des Uhrglases nach außen hin ist zweckmäßig, da bei hochwertigen Uhren das kratzfeste Safirglas bevorzugt Verwendung findet. Particularly preferably, the recess is formed completely in the carrier glass. Thus, the luminescent element is closer to a dial and the hands of a watch having the described watch glass. As a result, the intensity of the illumination of a illuminated by the luminescent element region of the dial is amplified. Alternatively, the recess may preferably be formed in the carrier glass. Thus, a larger area of the dial can be illuminated by the luminescent element. Another advantage of a recess with luminescent mass in the carrier glass is that then the cover glass can be free of recesses. This facilitates the use of saffron glass as a cover glass, which is much more difficult to recess with than the softer mineral glass of the support glass. The use of saffron glass as a cover glass or completion of the watch glass to the outside is expedient, since in high-quality watches, the scratch-resistant saffron glass is preferably used.
Weiter bevorzugt ist das lumineszierende Element in Richtung der Dicke der Glaseinheit mittig in der Glaseinheit aus dem Trägerglas und dem Deckglas angeordnet. Somit ist das lumineszierende Element vorzugsweise in einer zur Glaseinheit bzw. zur größeren Fläche der Glaseinheit senkrechten Richtung mittig in der Glaseinheit positioniert. More preferably, the luminescent element in the direction of the thickness of the glass unit is arranged centrally in the glass unit of the carrier glass and the cover glass. Thus, the luminescent element is preferably positioned centrally in the glass unit in a direction perpendicular to the glass unit or to the larger area of the glass unit.
Das lumineszierende Element kann vorzugsweise als Schmuckstein, insbesondere Diamant, und/oder Indiz und/oder Zeitmarkierungselement ausgebildet sein, wobei der Schmuckstein, das Indiz und das Zeitmarkierungselement lumineszierende Eigenschaften aufweisen. The luminescent element may preferably be formed as a gemstone, in particular diamond, and / or indicia and / or time marking element, wherein the gemstone, the indicia and the timing element have luminescent properties.
In vorteilhafter Weise ist die ganze Ausnehmung durch das lumineszierende Element ausgefüllt. Es befindet sich im Wesentlichen keine Luft in der Ausnehmung. Somit kann eine anderenfalls entstehende Lichtbrechung an der Grenze zwischen Luft und dem lumineszierenden Element vermieden werden. Dies führt dazu, dass kein Licht wegen einer solchen Lichtbrechung verloren geht bzw. zerstreut wird. Advantageously, the entire recess is filled by the luminescent element. There is essentially no air in the recess. Thus, an otherwise occurring refraction of light at the boundary between air and the luminescent element can be avoided. As a result, no light is lost or scattered due to such refraction of light.
Nach einer alternativen bevorzugten Ausgestaltung nimmt das lumineszierende Element die Ausnehmung nur teilweise ein. Dies erleichtert das Einbringen des lumineszierenden Elements in die Ausnehmung. Das ist besonders vorteilhaft, wenn ein als fluoreszierender Schmuckstein, insbesondere fluoreszierender Diamant, beispielsweise im Brillantschliff, ausgebildetes lumineszierendes Element vorgesehen ist. In diesem Fall nimmt das lumineszierende Element nicht die ganze Ausnehmung ein. Wenn z. B. fluoreszierende Schmucksteine, insbesondere natürliche fluoreszierende Diamanten verwendet werden, kann vorzugsweise im Innenraum der Uhr mindestens eine Schwarzlicht-LED angebracht sein, die die fluoreszierenden Diamanten von unten her beleuchtet und zum Fluoreszieren bringt. Es ist allerdings auch vorstellbar, dass eine Schwarzlicht-LED vorgesehen ist, wenn andere lumineszierende Elemente als fluoreszierende Schmucksteine benutzt sind. According to an alternative preferred embodiment, the luminescent element occupies the recess only partially. This facilitates the introduction of the luminescent element into the recess. This is particularly advantageous if a luminescent element designed as a fluorescent gemstone, in particular a fluorescent diamond, for example in brilliant cut, is provided. In this case, the luminescent element does not occupy the entire recess. If z. As fluorescent gems, especially natural fluorescent diamonds are used, preferably at least one black light LED can be mounted in the interior of the clock, which illuminates the fluorescent diamonds from below and brings to fluoresce. However, it is also conceivable that a black light LED is provided when other luminescent elements are used as fluorescent gems.
Um das Deckglas und das Trägerglas miteinander zu verbinden, ist eine Zwischenschicht zwischen dem Deckglas und dem Trägerglas vorgesehen. Die Zwischenschicht umfasst vorzugsweise eine selbstvernetzende Folie, insbesondere Polymerfolie und/oder Klebefolie, eine Silikonschicht und/oder einen Kleber, der insbesondere UV-aushärtbar ist. Dabei kann bevorzugt das lumineszierende Element in der Zwischenschicht angeordnet sein. Insbesondere ist das lumineszierende Element vollständig in der Zwischenschicht positioniert. In diesem Fall kann auf eine Ausnehmung im Deckglas und/oder im Trägerglas verzichtet werden. Bevorzugt ist eine Dicke des lumineszierenden Elements kleiner als eine Dicke der Zwischenschicht. Weiterhin ist beim Uhrglas bevorzugt eine Vielzahl von lumineszierenden Elementen vorgesehen, wobei die Elemente in einer Umfangsrichtung der Glaseinheit in der Glaseinheit angeordnet sind. Insbesondere liegen die lumineszierenden Elemente auf einem Kreis in der Glaseinheit. In order to join the coverslip and the carrier glass together, an intermediate layer is provided between the cover glass and the carrier glass. The intermediate layer preferably comprises a self-crosslinking film, in particular polymer film and / or adhesive film, a silicone layer and / or an adhesive, which is in particular UV-curable. In this case, the luminescent element may preferably be arranged in the intermediate layer. In particular, the luminescent element is completely positioned in the intermediate layer. In this case, can be dispensed with a recess in the cover glass and / or in the carrier glass. Preferably, a thickness of the luminescent element is smaller than a thickness of the intermediate layer. Furthermore, in the watch glass, a plurality of luminescent elements are preferably provided, the elements being arranged in a circumferential direction of the glass unit in the glass unit. In particular, the luminescent elements lie on a circle in the glass unit.
Die Ausnehmung und/oder das lumineszierende Element sind bevorzugt derart ausgebildet und/oder derart angeordnet, dass beim Leuchten des lumineszierenden Elements Licht aus mindestens 50 % einer Fläche der Unterseite des Trägerglases austretbar ist. The recess and / or the luminescent element are preferably designed and / or arranged such that when the luminescent element is illuminated, light can be emitted from at least 50% of a surface of the underside of the carrier glass.
Dabei wird das zunächst Licht aus der Lumineszenz nach oben hin austreten. Das Tageslicht oder ein Beleuchtungsmittel, welches die Lumineszenz anregt, wird hierbei zunächst die oberen Schichten der Leuchtmasse anregen und diese werden dann vermehrt ins Auge des Betrachters zurückstrahlen. In diesem Fall gibt die Leuchtmasse die Energie dann auch nach unten weiter, schon auch in Form von Licht, welches dann die tieferen Schichten der Leuchtmasse anregt. The first light from the luminescence will emerge upwards. The daylight or an illuminating means, which stimulates the luminescence, will in this case initially excite the upper layers of the luminous material and these will then increasingly reflect back into the eye of the observer. In this case, the luminous material then also passes the energy downwards, even in the form of light, which then excites the deeper layers of the luminous material.
Ferner sei angemerkt, dass unter dem Begriff „lumineszierende Element" bei der Formulierung „Licht tritt aus X% einer Fläche" auch eine Vielzahl von lumineszierenden Elementen zu verstehen ist. Mit anderen Worten gilt die vorstehende Aussage über den Prozentsatz auch wenn eine Vielzahl von lumineszierenden Elementen vorgesehen ist. It should also be noted that the term "luminescent element" in the formulation "light emerges from X% of a surface" also includes a multiplicity of luminescent elements To understand elements. In other words, the above statement about the percentage applies even if a plurality of luminescent elements are provided.
Ein weiterer Vorteil der Positionierung der leuchtenden Substanz (lumineszierende Elemente) im Uhrglas ist, dass die Lichtausbeute eben dieser Substanz ganz deutlich optimiert wird. Ist die Leuchtmasse am Boden des Innenraums der Uhr angebracht, also auf dem Zifferblatt oder auf den Zeigern, dann kommt nur jenes Licht zur Wirkung, welches nach oben, also zum Betrachter der Uhr hin abstrahlt. Jenes Licht, welches in die umgekehrte Richtung hin abstrahlt, also auf das Zifferblatt, bzw. auf die Zeiger, auf welchen die Leuchtmasse aufgesetzt ist, geht dem Betrachter verloren. Da in vorliegender Erfindung alles Material, welches das lumineszierende Element bzw. die lumineszierenden Elemente umgibt, transparent ist, wird eine nahezu 100%-ige Ausbeute des abstrahlenden Lichts. So kann die Wirkung der Leuchtmasse (egal ob z. B. eine chemische Substanz oder ein fluoreszierender Schmuckstein) erheblich optimiert werden. A further advantage of the positioning of the luminous substance (luminescent elements) in the watch glass is that the luminous efficacy of precisely this substance is very clearly optimized. If the luminous material is attached to the bottom of the interior of the clock, ie on the dial or on the hands, then only that light is effective, which radiates upward, that is to the viewer of the clock. That light which radiates in the opposite direction, that is to say on the dial, or on the hands on which the luminous substance is placed, is lost to the observer. In the present invention, since all the material surrounding the luminescent element (s) is transparent, a nearly 100% yield of the emitting light becomes. Thus, the effect of the luminous substance (no matter whether, for example, a chemical substance or a fluorescent gem stone) can be significantly optimized.

Ausführungsbeispiel der vorliegenden Erfindung.  Embodiment of the present invention.
Nachfolgend wird unter Bezugnahme auf die Figuren 1 und 2 ein Uhrglas 1 gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung im Detail beschrieben. Hereinafter, a watch glass 1 according to a first embodiment of the present invention will be described in detail with reference to Figs.
Die Fig. 1 zeigt eine Uhr 10 in der Form einer Armbanduhr mit einem Gehäuse 1 1 und einem erfindungsgemäßen Uhrglas 1 , welches im Gehäuse 1 1 angeordnet ist. Das Gehäuse 1 1 sowie das Uhrglas 1 sind kreisförmig ausgebildet, können allerdings jede andere Form wie z. B. eines Rechtecks, eines Polygons usw. aufweisen. Die Uhr 10 weist ferner ein Zifferblatt 12, welches beispielsweise als Goldblatt ausgebildet ist, sowie drei Zeiger 13 für die Anzeige der Stunden, Minuten und Sekunden, und zwei Anschlüsse für ein Armband 14 auf. Weiterhin umfasst die Uhr 10 ein Uhrwerk 7 zum Betreiben der Zeiger 13. Es sind natürlich auch Uhren denkbar, die nicht 3, sondern nur 2 Zeiger haben. Ferner ist das Uhrglas 1 mit lumineszierenden Elementen 5 versehen. Insbesondere sind hierbei vier lumineszierende Elemente 5 mit einem konstanten Radius in Umfangsrichtung mit gleichem Abstand voneinander im Uhrglas 1 angeordnet. Die Position sowie die Anzahl der lumineszierenden Elemente 5 können aber je nach Uhrdesign beliebig gewählt werden. So ist es zum Beispiel ebenso möglich, entweder nur ein lumineszierendes Element, oder auch zwei oder zwölf lumineszierende Elemente in das Uhrglas 1 einzubauen. Fig. 1 shows a clock 10 in the form of a wristwatch with a housing 1 1 and a watch glass 1 according to the invention, which is arranged in the housing 1 1. The housing 1 1 and the watch glass 1 are circular, but can be any other shape such. B. a rectangle, a polygon, etc. have. The watch 10 further includes a dial 12, which is formed for example as a gold leaf, and three hands 13 for the display of hours, minutes and seconds, and two connections for a bracelet 14. Furthermore, the clock 10 includes a movement 7 for operating the hands 13. Of course, watches are conceivable that have not 3, but only 2 pointers. Further, the watch glass 1 is provided with luminescent elements 5. In particular, in this case, four luminescent elements 5 are arranged with a constant radius in the circumferential direction at the same distance from each other in the watch glass 1. However, the position and the number of luminescent elements 5 can be chosen arbitrarily depending on the clock design. For example, it is also possible to incorporate either only one luminescent element or else two or twelve luminescent elements into the watch glass 1.
Die Fig. 2 ist eine vereinfachte, schematische Ansicht eines Schnitts A-A des Uhrglases 1 von Fig. 1 . Das Uhrglas 1 weist ein Trägerglas 2 und ein Deckglas 3 auf. Das Trägerglas 2 und das Deckglas 3 sind vorzugsweise aus unterschiedlichen Glasarten ausgebildet. Insbesondere ist das Trägerglas 2 ein Mineralglas und das Deckglas 3 ein Safirglas. Andere Glasarten können auch benutzt werden. So kann zum Beispiel das Trägerglas 2 aus Safirglas oder einem Polymerprodukt z. B. Plexiglas, und/oder das Deckglas 3 aus Mineralglas oder Plexiglas ausgebildet sein. Es ist im Rahmen der Erfindung möglich, unterschiedliche oder gleiche Glasarten zu kombinieren. Im Trägerglas 2 sind Ausnehmungen 4 ausgebildet, welche zur Aufnahme der lumineszierenden Elemente 5 dienen. In Figur 2 sind zwei solche Ausnehmungen 4 ersichtlich. Die Ausnehmungen 4 sind vorzugsweise ausschließlich im Trägerglas 2 ausgebildet. FIG. 2 is a simplified schematic view of a section A-A of the watch glass 1 of FIG. 1. The watch glass 1 has a carrier glass 2 and a cover glass 3. The carrier glass 2 and the cover glass 3 are preferably formed of different types of glass. In particular, the carrier glass 2 is a mineral glass and the cover glass 3 is a saffron glass. Other types of glass can also be used. For example, the carrier glass 2 made of saffron or a polymer product z. As Plexiglas, and / or the cover glass 3 made of mineral glass or Plexiglas be. It is possible within the scope of the invention to combine different or identical types of glass. In the carrier glass 2 recesses 4 are formed, which serve to receive the luminescent elements 5. In Figure 2, two such recesses 4 are visible. The recesses 4 are preferably formed exclusively in the carrier glass 2.
In jeder Ausnehmung 4 ist vorzugsweise das entsprechende lumineszierende Element 5 vollständig angeordnet. Dies bedeutet, dass das lumineszierende Element 5 bevorzugt die zugehörige Ausnehmung 4 komplett ausfüllt. In each recess 4, the corresponding luminescent element 5 is preferably arranged completely. This means that the luminescent element 5 preferably completely fills the associated recess 4.
Alternativ ist es möglich, dass die Ausnehmungen 4 nicht vollständig, also nur zum Teil, durch die lumineszierenden Elemente 5 ausgefüllt sind. Dies ist insbesondere der Fall, wenn fluoreszierende Schmucksteine, besonders bevorzugt fluoreszierende Diamanten, beispielsweise im Brillantschliff, als die lumineszierenden Elemente 5 benutzt werden. Alternatively, it is possible that the recesses 4 are not completely, so only partially, filled by the luminescent elements 5. This is the case in particular when fluorescent gemstones, particularly preferably fluorescent diamonds, for example in brilliant cut, are used as the luminescent elements 5.
Das Deckglas 3 und das Trägerglas 2 sind insbesondere kreisförmig ausgebildet und weisen denselben Durchmesser auf. Die Gläser 2, 3 unterscheiden sich in deren Dicke, wobei das Deckglas 3 vorzugsweise dünner geformt ist. Es ist aber auch möglich, dass die zwei Gläser 2, 3 dieselbe Dicke aufweisen. Weiterhin sind eine Innenfläche 20 des Trägerglases 2 und eine Innenfläche 30 des Deckglases 3 an der Kontaktstelle der zwei Gläser 2, 3 eben ausgebildet. Nach einer alternativen Ausgestaltung können aber die Innenflächen 20, 30 auch gleich und komplementär gewölbt sein. The cover glass 3 and the carrier glass 2 are in particular circular and have the same diameter. The glasses 2, 3 differ in their thickness, wherein the cover glass 3 is preferably thinner. But it is also possible that the two glasses 2, 3 have the same thickness. Furthermore, an inner surface 20 of the carrier glass 2 and an inner surface 30 of the cover glass 3 at the contact point of the two glasses 2, 3 are flat. According to an alternative embodiment, however, the inner surfaces 20, 30 may be curved the same and complementary.
Das Deckglas 3 und das Trägerglas 2 sind über eine verbindende Zwischenschicht 6 (Verbindungsschicht) miteinander verbunden. Die Zwischenschicht 6 kann insbesondere als Klebefolie, Laminierfolie, Klebstoff oder eine andere Verbindungsmasse ausgebildet sein. Die Zwischenschicht 6 ist zwischen dem Deckglas 3 und dem Trägerglas 2 angeordnet. Zwischen dem Deckglas 3 und dem Trägerglas 2 ergibt sich somit eine nahtlose, luftdichte Verbindung. The cover glass 3 and the carrier glass 2 are connected to one another via a connecting intermediate layer 6 (connecting layer). The intermediate layer 6 can in particular as Adhesive film, laminating film, adhesive or another compound may be formed. The intermediate layer 6 is arranged between the cover glass 3 and the carrier glass 2. Between the cover glass 3 and the carrier glass 2 thus results in a seamless, airtight connection.
Die lumineszierenden Elemente 5 können in vorteilhafter Weise Licht (Pfeile 100), insbesondere Sonnenlicht, bei deren Beleuchtung speichern und bei Dunkelheit wieder abgeben (Pfeile 101 ). The luminescent elements 5 can advantageously store light (arrows 100), in particular sunlight, during their illumination and release it again in the dark (arrows 101).
Zum Herstellen des Uhrglases 1 werden zunächst das Deckglas 3, das Trägerglas 2 und die lumineszierenden Elemente 5 bereitgestellt. In das Trägerglas 2 werden die Ausnehmungen 4 zum Aufnehmen der lumineszierenden Elemente 5 eingebracht. Danach werden die lumineszierenden Elemente 5 in die Ausnehmungen 4 eingesetzt. To produce the watch glass 1, first the cover glass 3, the carrier glass 2 and the luminescent elements 5 are provided. The recesses 4 for receiving the luminescent elements 5 are introduced into the carrier glass 2. Thereafter, the luminescent elements 5 are inserted into the recesses 4.
Auf das Trägerglas 2 wird die Zwischenschicht 6 aufgebracht. Die Zwischenschicht 6 kann, wie schon beschrieben, eine selbstvernetzende Polymerfolie, eine dünne Silikonschicht, ein UV-aushärtender Kleber oder ein sonstiges verbindendes Material sein. Nach dem Aufbringen der Zwischenschicht 6 wird das Deckglas 3 auf die Zwischenschicht 6 aufgebracht. Hierbei wird bevorzugt die Zwischenschicht 6 unter Vakuum und gleichzeitig unter Druck von oben und unten erhitzt. So werden das Trägerglas 2 und das Deckglas 3 dergestalt miteinander verbunden, dass die lumineszierenden Elemente 5 zwischen den beiden Gläsern 2, 3 fest eingebunden werden, und dass das ganze Gebilde eine feste Glaseinheit 8 wird. Das zweite Ausführungsbeispiel von Fig. 3 unterscheidet sich vom ersten Ausführungsbeispiel von Figuren 1 und 2 grundsätzlich dadurch, dass im Uhrglas 1 keine Ausnehmungen ausgebildet sind. Stattdessen sind die lumineszierenden Elemente 5 vorzugsweise in die Zwischenschicht 6 eingebettet. Insbesondere liegen die lumineszierenden Elemente 5 auf der Innenseite 20 des Trägerglases 2. Das Herstellverfahren des Uhrglases 1 gemäß dem zweiten Ausführungsbeispiel entspricht dem Herstellverfahren des Uhrglases 1 gemäß dem ersten Ausführungsbeispiel bis auf die Schritte des Einbringens von Ausnehmungen in das Trägerglas 2 und das Einsetzen der lumineszierenden Elemente 5 in Ausnehmungen. On the carrier glass 2, the intermediate layer 6 is applied. The intermediate layer 6 can, as already described, be a self-crosslinking polymer film, a thin silicone layer, a UV-curing adhesive or some other bonding material. After the application of the intermediate layer 6, the cover glass 3 is applied to the intermediate layer 6. In this case, the intermediate layer 6 is preferably heated under vacuum and at the same time under pressure from above and below. Thus, the carrier glass 2 and the cover glass 3 are connected to each other in such a way that the luminescent elements 5 between the two glasses 2, 3 are firmly integrated, and that the whole structure is a solid glass unit 8. The second embodiment of Fig. 3 differs from the first embodiment of Figures 1 and 2 in principle in that in the watch glass 1 no recesses are formed. Instead, the luminescent elements 5 are preferably embedded in the intermediate layer 6. In particular, the luminescent elements 5 are located on the inner side 20 of the carrier glass 2. The manufacturing method of the watch glass 1 according to the second embodiment corresponds to the manufacturing method of the watch glass 1 according to the first embodiment except for the steps of introducing recesses in the carrier glass 2 and the insertion of the luminescent Elements 5 in recesses.
Hier werden nach der Bereitstellung des Trägerglases und des Deckglases die lumineszierenden Elemente 5 auf das Trägerglas 2 aufgelegt. Danach wird die Zwischenschicht 6 auf das Trägerglas 2 bzw. die lumineszierenden Elemente 5 aufgebracht. Here, after the provision of the carrier glass and the cover glass, the luminescent elements 5 are placed on the carrier glass 2. Thereafter, the intermediate layer 6 is applied to the carrier glass 2 or the luminescent elements 5.
Die weiteren Schritte zum Verbinden des Trägerglases 2 mit dem Deckglas 3 entsprechen denen des Ausführungsbeispiels. Es sei angemerkt, dass in den vorstehend beschriebenen Ausführungsformen der Erfindung das Uhrglas 1 zwei Gläser (Deckglas und Trägerglas) umfasst. Es ist allerdings möglich, dass das Uhrglas 1 mehrere Gläser aufweist, wobei nacheinander folgende Gläser, insbesondere durch eine Zwischenschicht, miteinander verbunden sind. The further steps for connecting the carrier glass 2 to the cover glass 3 correspond to those of the exemplary embodiment. It should be noted that in the embodiments of the invention described above, the watch glass 1 comprises two glasses (cover glass and carrier glass). However, it is possible that the watch glass 1 has a plurality of glasses, successively following glasses, in particular by an intermediate layer, are interconnected.
